CROSS-REFERENCE TO RELATED APPLICATIONS

This application claims the benefit of U.S. Provisional Application No. 60/484,912 filed Jul. 3, 2003 which is hereby incorporated by reference in its entirety.

BACKGROUND OF THE INVENTIONS

Known in the art are electrical boxes intended to enclose wiring and connectors, those boxes also optionally including mountings for securing a lighting fixture. Certain of those boxes are suitable for mounting overhead just above a ceiling, attaching to a truss, joist or other structural support member. In a typical new installation metal or, more frequently, plastic light-duty boxes are installed, those being the most inexpensive type suitable for carrying a light-weight lighting fixture, for example a fixture housing a single medium-base bulb. It is often the case that a homeowner will wish to later install a heavier fixture, such as a ceiling fan or chandalier, to the originally installed electrical box. Many homeowners are not aware of the unsuitability of these light-weight boxes for those applications, and many install these heavier fixtures improperly and dangerously without upgrading the support structure.

A ceiling fan, through normal operation, may create oscillatory stresses on the electrical box it is attached to. If attached to a light-duty box, these forces may carry through the fan support to the electrical box, which may cause the box to twist slightly on each oscillation. Over time this motion may cause the nails, or other fasteners, used to secure the electrical box to move and/or loosen, which may lead to failure of the electrical box supporting structure. Additionally, if the box structure is not sufficiently rigid, forces may be transferred to the drywall, or other material, of the ceiling. Now drywall, plaster, paneling and most other ceiling materials are not designed to carry loads. These materials may carry a load briefly, but over time cracks may develop leading to an unpredictable failure of the material. If both the electrical box supporting structure and the ceiling material fail, the result is a fixture falling at an unpredictable time, which can lead to property damage, personal injury and litigation against the makers of the ceiling fan, lighting fixture, electrical box manufacturer as well as other involved parties.

In many areas earthquakes are a concern. A non-moving ceiling fixture mounted to a light-weight box may carry a load sufficiently well under static conditions for many years. Earthquakes are unpredictable events that may occur at any time, and in some locations with such severity as to cause large thrust and oscillatory motions on the lighting fixture and electrical box. A homeowner may be completely unaware of a dangerously supported fixture until a tremor causes it to fall. The dangers of inadequately supported lighting fixtures therefore encompasses more fixtures than ceiling fans.

Now there are several electrical box types which will support a relatively heavy load, of which several are represented in U.S. patents. A usual type, represented by U.S. Pat. No. 6,242,696, utilizes wings attached to the side of the electrical box to attach to a structural member. This type requires installation prior to the installation of a finished ceiling to avoid damage thereto. Another type, represented by U.S. Pat. Nos. RE 38,120, 6,107,568, 6,191,362, 6,207,897 and 6,355,883, envisions a ceiling electrical box that attaches to an overhead structural support member from underneath through the use of screws or other fasteners generally driven upward through the top of the box and into the structural member. Those boxes either include a slot fitting the support member, or are designed to fit in a space between the support member and the surface of the finished ceiling. All of those designs have the disadvantage of reduced internal box volume, by which the number of electrical connections and wires is restricted over a common side-mounted nailed electrical box. Another type, represented by U.S. Pat. Nos. RE 33,147, 6,098,945, 6,465,736, and 6,595,479, utilizes an extendable rod or other structure fittable between the space between two joists or structural members. This type of electrical box, although avoiding impacts into the volume of the electrical box, carries a number of disadvantages. First, the use of the rod introduces a substantial lever arm; the rod must therefore be fairly heavy to avoid bowing under the fixture load. This type of box is typically constructed of steel or other metal, as the needed plastic supports would be very thick in comparison. These boxes tend are more complex and require more materials and building steps to fabricate. The cost of this type of box also tends to be much higher to the end user. A final type, represented in U.S. Pat. Nos. RE 34,603 and 6,100,469, utilizes fasteners through a metal electrical box sidewall into the adjacent structural member. This type relies on the strength of the sidewall to avoid the fastener head pulling through the sidewall material under load, and is therefore unsuitable for plastic materials. Furthermore, this type relies on the box structure to resist a downward force, which may place strain on welds and joints. Additonally, fasteners driven in a substantially horizontal direction limit the amount of driving force that can be applied to the fastener and may make installation difficult without specialized tools. And none of these box types provide a method of upgrading a ceiling electrical box to carry additional load.

Thus, some of these boxes are relatively expensive to produce and install, while others may be installed only by creating new holes in a ceiling or otherwise causing new damage that must be repaired. In the market there is a general lack of products and methods that provide for upgrading of ceiling electrical boxes to support heavier loads. There is therefore a need for products which can create a box structure capable of supporting more than a light load which can be installed without causing damage to an existing ceiling.

DETAILED DESCRIPTION

Disclosed herein are several brackets useful for reinforcing electrical boxes installed adjacent to a structural member, such as a truss or joist. Shown in FIG. 1 is an example of one particular reinforcment device in the form of a bracket designed for two specific electrical box types, although it might be installed in others. Bracket 11 a includes two largely planar portions, 12 a and 15 a, connected by bend 17 a. Planar portion 12 a, in this example, forms an interface providing a mating to the top of an electrical box at the inside. The ends of planar portions 12 a and 15 a are shaped to form an interface to the side of an electrical box at the inside, that interface being shown at 13 a and 14 a. In this example, ends 13 a and 14 a provide two interfaces for two specific electrical box types, as will be discussed presently, one interface provided at 13 aa and 14 aa for a substantially flat electrical box sidewall and another interface at 13 ab and 14 ab for a screw boss, which are integral in many plastic electrical ceiling boxes. Planar portion 15 a provides a strut-like portion providing resistance to a compressive force applied between the top and side interfaces. That strut-like portion functions to at least partially convert a downward force on the electrical box to a horizontal force in the direction of the structural member. In bracket 11 a, two fastener features, in this example recesses, 16 aa and 16 ab (shown 16 a in FIG. 1 b) provide attachment points for screws. Recesses 16 aa and 16 ab are oriented so that fasteners inserted therein may fasten the bracket 11 a through the electrical box sidewall and into an adjacent structural member. In this example, recesses 16 aa and 16 ab are configured to align fasteners at approximately 60 degrees from the vertical for an electrical box mounted to a vertical structural member surface. This permits the fasteners to be driven into the structural member with a single tool, such as an ordinary screwdriver or hammer, through many electrical box openings. It is preferred that this angle and the position of any fastener features be set so as to permit ease of access to the fasteners using ordinary tools, although other angles or positions may be chosen without departing from the larger scope of the invention. Preferably, the driving force may be directly applied by a tool external to the electrical box, for example a screwdriver or hammer. Recesses 16 aa and 16 ab may include a substantially cylindrical portion, not shown, for guiding the fastener at a desired angle relative to the bracket. In this example, recesses 16 aa and 16 ab provide seats for screws, which recesses are not threaded to provide free movement so that bracket 11 a may be brought tightly into a supportive position. A bend 18 a is provided near end 14 a to orient that end perpendicular to the electrical box sidewall providing for transverse motion by which bracket 11 a may be brought more snugly into a supportive position during installation of the bracket.

The bracket 11 a of FIG. 1 may be fashioned utilizing ordinary sheet-metal die-processing procedures to make the various bends and and shapes of the bracket, as well as other reinforcing brackets. Preferred materials for reinforcing brackets, such as 11 a, include zinc-plated mild steel, due to that material's strength, durability, widespread availability and applicable manufacturing facilities. Other metals may be used, such as aluminum, brass or “pot” metals, keeping in mind that different thicknesses may be required to achieve necessary strength and bracing characteristics. Processes other than die processes may be used as desired, for example extrusion processes, particularly where a bracket is to be made from aluminum or its alloys.

Shown in FIG. 2 is a four inch plastic electrical box 20 a with bracket 11 a installed; FIG. 2 a showing a perspective view through the electrical box opening, FIG. 2 b showing a bottom view, and FIG. 2 c showing a sectional view through axis 1. Electrical box 20 a includes an aperture through which access is permitted to manipulate wires inserted into the electrical box and to make connections thereto. Electrical box 20 a includes flanges 22 a for holding nails 23 in a relative position whereby nails 23 may be driven into a support member to secure the box 20 a into position. When bracket 11 a is in installed position, top mating interface 12 a (not shown) rests against the electrical box top inside surface 26 a, while side interface 14 aa resting against a flat portion 21 a of electrical box sidewall. Screws 24 are driven through bracket 11 a and sidewall 21 a into the structural member to secure the bracket 11 a into installed position.

Bracket 11 a is designed to reinforce two particular box types. FIG. 3 shows a three inch plastic electrical box 20 b with bracket 11 a intalled therein, with FIG. 3 a showing a perspective view through the electrical box opening; FIG. 3 b showing a view looking at the bottom, and FIG. 3 c showing a sectional view through axis 3. Electrical box 20 b also includes flanges 22 b for fastening the box 20 b to a structural member by way of nails 23. For this box, the installation position of bracket 11 a also brings top mating surface 12 a (not shown) against electrical box top inside surface 26 b. This electrical box 20 b includes a boss 25 b for insertion of a mounting screw, whereby a fixture may be attached to electrical box 20 b. Bracket 11 a rests against boss 20 b at the side interfaces 14 ab and optionally 13 ab (not shown). Screws 24 are likewise driven through bracket 11 a and sidewall 21 b into the structural member to secure the bracket 11 a into installed position.

The design of bracket 11 a permits use in metallic electrical boxes as well. In FIG. 4 bracket 11 a is shown installed into a 3 inch metal-type electrical box 20 c, with FIG. 4 a showing a view from the box bottom, FIG. 4 b showing a sectional view through axis 2, and FIG. 4 c showing a perspective view. This electrical box 20 c includes alignment wings 22 c with holes pre-formed to permit fastening to a structural member with nails, screws, or other fasteners. As in the plastic boxes, bracket 11 a mates top mating surface 12 a against the top of the electrical box 26 c, and also mates side interface 14 aa against electrical box sidewall 21 c. To secure, screws 24 are driven through bracket 11 a and sidewall 21 c into the structural member, although pre-drilling of holes through sidewall 21 c may be necessary if holes are not formed therein prior to installation.

FIG. 5 further illustrates the installation of two brackets of the type shown in FIG. 1 using two electrical box types; FIG. 5 a showing a view looking up through the bottom of the electrical boxes and at the ceiling, FIG. 5 b showing a sectional view about the axis labeled 4, and FIG. 5 c showing an inverted perspective view (turned upside down for ease of viewing). Ordinary and modern construction utilizes wood structural members, of which one member 30 is shown. Member 30 might be the lower portion of a truss, a joist, or other structural member upon which a ceiling is to be fashioned. Ordinary construction utilizes drywall 31 fastened by nails or screws to structural members, one screw 32 being shown. Also shown are a four inch plastic electrical box 26 a of the type of FIG. 2 and one three inch plastic electrical box 26 b of the type of FIG. 3. Both boxes 26 a and 26 b are normally installed prior to drywall application to structural member 30 through flanges, one 22 b being shown, and nails 23. Drywall 31 is applied afterward, and holes cut therein to provide access to the interior of the electrical boxes. After drywall 31 is installed, access to structural member 30 may be restricted, particularly if there is little or no access space surrounding structural member 30. In other situations access may be inconvenient, for example where structural member 30 is the lower part of a truss accessible through an attic or other space. A bracket 11 a may be installed without direct access to structural member 30 through the interior of the box. The bracket 11 a is inserted into the box and placed in proper mounting position, next to the electrical box sidewall adjacent to the structural member. Screws 24, or other fasteners, are then driven through the bracket 11 a, the electrical box sidewall 21 a or 21 b and into the structural member 30. FIG. 5 b includes a cutout 33 area to show screw 24 clearly.

An electrical box may optionally have a reinforcing bracket built in. FIGS. 6 a-d show conceptually how this might be done in a metal-type box. Referring to FIG. 6 a, an electrical box 40 a is made in an intermediate stage, the box having a top 45, sides, and an unbent flap 41. Electrical box 40 a may be fashioned from usual processes for electrical box manufacture, including stamping, pressing, punching, spot welding and other techniques. In this example and prior to this stage, fastener features 42 have been stamped prior to the next step. Those fastener features might be, for example, screw guides, nail guides, or conical or countersunk structures for securing a screw head. In that step, flap 41 is bent as shown in FIG. 6 b, to form a brace 43 and a top interface portion 44 meeting with top 45. Now it is to be understood that this step may actually include several successive steps in which bends are progressively made to flap 41. FIG. 6 c also shows the completed configuration as seen through the bottom of the box. FIG. 6 d shows a sectional view through the axis labeled 5. Now although it is not shown, sidewall 46 is preferably pre-punched or drilled with holes for fasteners to pass through when inserted in 42, by which the installer may avoid drilling operations. This electrical box does not include wings or other extra-box support structures, but rather relies on the bracing structure formed by brace 43 and top interface portion 44 to stabilize the attachment of the electrical box 40 b to a structural member. Preferably, at least three fastener features are included, as shown, in at least two axes to form a tri-point securement geometry. Electrical box 40 b may be considered to be an “old work” or “rework” type box, as it may be conveniently installed to a finished ceiling. To do so, an installer would (1) find an attachable structural member, (2) cut a matching hole in the drywall, paneling, or other wall structure so the electrical box may be positioned next to the structural member, (3) insert the box and (4) fasten the box to the structural member through fastener features 42.

FIG. 7 shows an alternate bracing electrical box 50 having three flanges. Those flanges include two horizontal flanges 51, which are included in conventional electrical boxes. An additional flange 52 is added substantially outside the plane formed by flanges 51, in this example attached to and above the electrical box top 54. Nails 53 are driven into a structural member during installation. Without the use of flange 52 and corresponding nail 53 a, a weighted box has a tendency to rotate about an axis passing through the points where the nails 53 b enter the structural member, where the most stress occurs in the nail material. Flange 52 and nail 53 b, when used, prevent this rotation and keep the box in a more stable position. Now this box is more useful for new construction, as the task of driving the nails would be most difficult without tearing out a large section of wall necessary to swing a hammer or insert a power tool.

FIG. 8 shows another bracing electrical box 60 a having conventional flanges 61 and an integrated bracket 62 a, FIG. 8 a showing a perspective view of the box internal space, FIG. 8 b shows a view of the outside of the box looking at the sidewall in adjacency to the bracket, FIG. 8 c shows a bottom view of the box and FIG. 8 d shows a sectional view in the axis marked 6. In this example, bracket 62 a is molded out of plastic and integral to the structure of the electrical box. Ribbing 63 may be provided to resist the force applied by fasteners 64 when attached, while minimizing the amount of plastic material needed. This particular electrical box is useful for new installations where access to the structural member is not restricted.

Shown in FIG. 9 is an alternate electrical box 60 b, with FIGS. 9 a and 9 b showing two different perspective views to the interior of the box. Electrical box 60 b has the same integrated bracket 62 a and ribbing 63 as box 60 a of FIG. 8, but omits flanges 61. This box may be installed in a similar manner to the box 40 a of FIG. 6, and is considered to be an “old work” type box.

FIG. 10 shows another bracing electrical box 60 c having conventional flanges 61 and an insert molded bracket 62 b, FIG. 10 a showing a perspective view of the box internal space, FIG. 10 b showing a view of the outside of the box looking at the sidewall in adjacency to the bracket, FIG. 10 c shows a bottom view of the box, FIG. 10 d showing a sectional view in the axis marked 7, and FIG. 10 e showing the detail in the area marked 8. In this example, bracket 62 b is molded in place during the molding process. Bracket 62 b might be made of any stiff, strong and temperature insensitive material, for example steel, aluminum, brass, wood, carbon fiber, or other metal alloy or composite material, that withstands the temperatures of the plastic molding process and provides the desired reinforcement. Bracket 62 b is placed in appropriate position inside the electrical box mold at the time the plastic part of the box is fabricated, the plastic generally encompassing or surrounding the bracket sufficiently to hold the bracket in place so that it does not become dislodged through ordinary use. Additional thicknesses of plastic material may be fashioned at the points of stress, for example 66 where bracket 62 b meets the sidewall of the box and more particularly 65 where bracket meets the top of the box. Electrical box 60 c is considered to be a “new work” type box.

FIG. 11 shows an alternate electrical box 60 d similar to the box 60 c of FIG. 10, with FIGS. 10 a and 10 b showing two different perspective views to the interior of the box. Electrical box 60 d has the same insert molded bracket 62 b as box 60 a of FIG. 10, but omits flanges 61. This box may also be installed in a similar manner to the box 40 a of FIG. 6, and is considered to be an “old work” type box. Now the above described boxes may include alignment features, such as tabs, to align the electrical box into proper position with respect to the ceiling surface, particularly if the boxes are intended for old-work installations.

FIG. 12 shows an alternate configuration of a reinforcing bracket 11 b, including FIGS. 12 a and 12 c showing perspective views and FIG. 12 b showing a side view. This bracket 11 b includes a substantially flat surface 12 b for mating with the top of an electrical box. Mating surfaces 13 b and 14 b are provided to rest against an electrical box sidewall, that sidewall preferably being flat. Two legs 15 b extend between mating surfaces 13 b and 14 b connecting the bracket portion including mating surface 12 b with the bracket portions containing fastener features 16 b. A separation 19 is provided between the two legs 15 b to permit mounting around an obstruction in the electrical box, for example a screw boss. The compressive portion of this bracket 11 b is small, and is mainly around the bend at 13 b. Because of this, this bracket is preferably constructed of stiffer and/or stronger materials than that of 11 a to maintain a similar bracing capacity.

FIG. 13 shows another alternate configuration of a reinforcing bracket of the type of 11 a, FIGS. 13 a and 13 c showing perspective views and 13 b a side view. Bracket 11 c includes a top mating interface 12 c, fastener features 16 c, and a strut portion 15 c. This bracket is intended to fit an electrical box having a substantial cylindrical sidewall, for example the 3 inch ceiling electrical box shown in FIG. 3, and thus curved regions 13 ca and 14 ca are provided to mate thereto. Side interface areas 13 cb and 14 cb may be used to mate to a fastener boss, as in the bracket of 11 a. Bends 17 c and 18 c are included to orient strut portion 15 c, top mating surface 12 c, and side interface areas 13 ca, 13 cb, 14 ca and 14 cb in positions that will mate well with the intended electrical boxes, provide reinforcement and orient fastener features in a direction that assists the insertion of fasteners therein into a structural member. Bracket 11 c may be made using similar methods and materials as to that of bracket 11 a.

Now it is preferred that reinforcement brackets, devices or features be designed to consume a minimal amount of the interior volume, so as to maximize the number of wires and electrical connections that can be made within the electrical box.

A kit containing a reinforcement device and necessary fasteners may be advantageously assembled for the convenience of the installer. Such a kit might be included, for example, in the product packaging of an electrical applicance, for example a ceiling fan or lighting fixture, providing added convenience to the installer of the product in situations where the use of the bracket is desirable. A fastener bit suitable for insertion into a drill may also add to the convenience of the installer at a reasonable expense.

A preferred fastener type for use with reinforcement devices and brackets is the pilotless screw, as commonly used in decking, fencing and drywall applications. That type of screw can be driven into woods used for construction as well as many plastics with minimal splitting and/or stretching of the material. The use of that type of screw simplifies the installation of the bracket by reducing the need for drilling pilot holes, which under many circumstances will be awkward given the overhead working position and the restrictions of available access to the interior of the particular electrical box, and further require the use of long drill bits or adapters which may not be in the equipment inventory of typical installers. The use of screws is also preferred to mitigate the effects of thermal and humidity cycles, which is a known problem with nails.

While reinforcing brackets, devices, and electrical boxes containing reinforcement and the use of those have been described and illustrated in conjunction with a number of specific configurations and methods, those skilled in the art will appreciate that variations and modifications may be made without departing from the principles herein illustrated, described, and claimed. The present invention, as defined by the appended claims, may be embodied in other specific forms without departing from its spirit or essential characteristics.
